Linus Torvalds 17fda38f15 Vince Weaver reported a warning when he added perf event filters ... into his fuzzer tests. There's a missing check of balanced operations when parenthesis are used, and this triggers a WARN_ON() and when reading the failure, the filter reports no failure occurred. The operands were not being checked if they match, this adds that. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJVgWlDAAoJEEjnJuOKh9ldPrUH/0JPSQsQ6luazLvzicqDaDe6 CIWw3sygSeKrD/IWfEZqlUZFI0fmUu4F61BPimwMZ2i03epT5hEO1EgVnuYK9EX6 jjrSXIinC8TzSG2+SGM+fITPgByAwT6wg2fadV5RvX6ymERO+pari1mUfLAKQeit /Ai+CsRsQTfh63c998hDtULrLHk/RkQy2GE5p1oF/+peo/1P35LL2BVtOIOWUvMZ Zf0T58LmSp7QmwGrJm+Wl3FewuwhOErqgTbxbAn15tXZoYzF4uuH2dU/pcHgAYwB O1ERVc7IhYIwj2O0GeUfTVS1Ukdq6qbZyfPgBFnWksEz97DiFsCmIQKLzGgbdsk= =avE6 -----END PGP SIGNATURE----- Merge tag 'trace-fix-filter-4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing filter fix from Steven Rostedt: "Vince Weaver reported a warning when he added perf event filters into his fuzzer tests.
